What is a programmable room thermostat?
The SunStatRF is a wireless programmable room thermostat. A
SunStat should be purchased if a wired version of the same unit is
required.
A programmable room thermostat is both a programmer and a
room thermostat. A programmer allows you to set 'On' and 'Off'
time periods to suit your own lifestyle. A room thermostat
works by sensing the air temperature, switching on the heating
when the air temperature falls below the thermostat setting,
and switching it off once this set temperature has been
reached.
Thermostat position
So, a programmable room thermostat lets you choose what
times you want the heating to be on, and what temperature it
should reach while it is on. It will allow you to select different
temperatures in your home at different times of the day (and
days of the week) to meet your particular needs.
Disconnect the mains supply before attempting to wire the unit, or
removing unit from back plate. A switch having a contact separation
of at least 3mm in all poles must be incorporated in the fixed wiring as
a means of fully disconnecting the mains supply. An appropriate fuse
should also be fitted to the circuit.
Turning a programmable room thermostat to a higher setting
will not make the room heat up any faster. How quickly the
room heats up depends on the design of the heating system,
for example, the size of boiler and radiators.
Neither does the setting affect how quickly the room cools
down. Turning a programmable room thermo stat to a lower
setting will result in the room being controlled at a lower
temperature, and saves energy.
The way to set and use your programmable room thermostat is
to find the lowest temperature settings that you are
comfortable with at the different times you have chosen, and
then leave it alone to do its job. The best way to do this is to
set low temperatures first, say 18°C, and then turn them up by
one degree each day until you are comfortable with the
temperatures. You won't have to adjust the thermostat further.
Any adjustments above these settings will waste energy and
cost you more money.
If your heating system is a boiler with radiators, there will
usually be only one programmable room thermostat to control
the whole house. But you can have different temperatures in
individual rooms by installing thermostatic radiator valves
(TRVs) on individual radiators. If you don't have TRVs, you
should choose a temperature that is reasonable for the whole
house. If you do have TRVs, you can choose a slightly higher
setting to make sure that even the coldest room is comfortable,
then prevent any overheating in other rooms by adjusting the
TR V s.
The time on the programmer must be correct. Some types
have to be adjusted in spring and autumn at the changes
between Greenwich Mean Time and British Summer Time.
You may be able to temporarily adjust the heating programme,
for example, 'Override', 'Advance' or 'Boost'. These are
explained in the manufacturer's instructions.
Programmable room thermostats need a free flow of air to
sense the temperature, so they must not be covered by
curtains or blocked by furniture. Nearby electric fires,
televisions, wall or table lamps may prevent the thermostat
from working properly.
SunStatRF User Instruction Leaflet: LE/0222/7051/0001/01
The thermostat should be placed at a height of 1.5m from the floor.
Do not position on an outside wall, above a radiator, next to a door, or
in direct sunlight.
For fixed wiring only
WARNINGS
All installations should be carried out by a
competent person and in line with current
wiring regulations.
The covers must not be removed from any
part of the units before the electrical supply
has been isolated.
Interference with sealed parts will render the
guarantee void.

Copy Function
The copy function allows a program setting to be copied from one day
to any number of the remaining days.
1)
Use the rotary selector switch to select the day which will be
used as the source (Monday for example).
2)
Check, if necessary, that the “day” to be used as the source
program has been programmed correctly, using the above
“setting the program” procedure.
3)
When satisfied that the source day, in this case Monday, has
been programmed correctly press
button.
4)

It is possible to set 4 different programs for each day of the week.
Each program comprises of 1 temperature and time set points. 4
symbols are used to differentiate the programs.

The thermostat will hold the room temperature at the required set
point within each programmed time zone. At the next programmed
time zone the temperature can be changed, if required, to a
different temperature setting.
The program resolution is in 10 minutes intervals. The first interval
of the day starts at 00.00 is the last interval of the day starts at
23.50.
The programming is designed to allow users to “overlap” time
zones, if required. If an “overlap” is selected the number of
programmes will reduce by the number of “overlaps” For example
if the start up time of P3 is the same as the start up time of P4,
then the P3 operation will become an invalid command.

17) For example, if during the copying process Tuesday,
Thursday and Friday have been selected as the days
requiring the ”source day” program to be copied to, the
display will show.

Remove the display unit from the back-plate by loosening the
retaining screw on the left hand side of the unit and then lightly
pull the display unit away from the back-plate.
e)
The battery compartment is located on the inside of the display
unit.
f)
Replace the batteries, taking care that they are orientated
correctly and then re-fit the display unit to the back-plate and
then tighten the retaining screw.
g)
Always replace both (2) batteries at the same time. Only use
1.5V alkaline batteries of the type LR06 (AA).
h)
Do not dispose of batteries with household rubbish. They must
be returned in accordance with the local statutory requirements.
User Note
If the batteries need to be changed the RF link may be lost.
In such an instance the manual override, on the receiver
unit, can be used to temporarily switch the heating ON or
OFF until such time as the batteries have been changed.
